In a stunning situation, a Florida husband and wife who were diagnosed with brain tumors just four months apart have beaten the odds and have both completed treatment.

In March 2018, Grady Elwell, 42, was diagnosed with a rare malignant brain tumor that would require months of surgeries, chemotherapy and radiation.

As his wife, Beth Kassab, made a to-do list of specialists to see and family to break the news to, she decided to make an appointment to have her ear checked.

It had been hurting and ringing for the past few weeks and she assumed she had an infection or that she was stressed by the news of her husband's cancer.

However, four months later, in July 2018, tests confirmed Kassab had her own brain tumor that would require surgery to be removed.

Now, nearly a year later, both appear to be in remission.

In a first-person account for the Orlando Sentinel, Kassab, who is the newspaper's enterprise editor, discussed the fear that their two children would be left without parents and doctors telling them the chance they would both have brain tumors was more than one in a million.

According to a Facebook post, Kassab said her husband's troubles began when he randomly had a seizure at home in January 2018, despite no history of seizures.

After several MRIs, doctors determined that he needed a biopsy.

In March 2018, a few days later, Elwell was diagnosed with anaplastic astrocytoma - a grade III brain tumor - at the University of Florida Health in Gainesville.

A rare, malignant brain tumor, it develops from star-shaped brain cells called astrocytes that form tissue to surround and protect other nerve cells within the brain and spinal cord.

It occurs in about five to eight people per 100,000 in the general population, according to the National Organization for Rare Disorders.

The five-year survival rate is 23.6 percent and patients with this type of tumor are 46 times more likely to die than the general population.

Doctors told him he would need daily radiation and chemotherapy, which began in June, Kassab wrote in the Sentinel.

Last year, although exactly when is unclear, Kassab underwent Gamma Knife surgery, a form of radiation treatment specifically used to treat tumors, vascular malformations and 'other abnormalities in the brain'.

It delivers high doses of radiation to a target area with the precision of a scalpel.

Elwell has undergone multiple surgeries and has completed his chemotherapy and radiation treatment plan.

Kassab wrote that the couple even plans to run in a race this weekend 'to raise money and awareness for brain cancer'.

Despite feeling unlucky when they first received their diagnoses, Kassab says that she and Elwell were able to get paid time off from their jobs, insurance that covered their treatments and family and friends that pitched in to help - which many people don't get.

'In many ways, we were a textbook case for exactly how the healthcare system should work,' she wrote in the Sentinel.

'Many Americans are forced to crowd-source their way through medical emergencies. By comparison, Grady and I had it easy.'
